Pulse-position modulation — is a form of signal modulation in which M message bits are encoded by transmitting asingle pulse in one of 2^M possible time shifts. This is repeated every T seconds, such thatthe transmitted bit rate is M/T bits per second. It is primarily… … Wikipedia
Ring modulation — is a signal processing effect in electronics, related to amplitude modulation or frequency mixing, performed by multiplying two signals, where one is typically a sine wave or another simple waveform. It is referred to as ring modulation because… … Wikipedia
